I have a cistern in my garage with a pump connected to it which allows the house to receive water. I recently had to change 2 plastic pipes and after I did this the water pressure is no worse. I checked that the pump was primed and it was and I do get some pressure but the pressure is much worse. Any ideas?

I recently had to change 2 plastic pipes Explain to me about these two pipes you replaced? Since plastic doesn't wear out why were they replaced? Back to you, Tom

"after i did this the water pressure is no worse." I am assuming you meant to say the pressure is NOW worse. I'm with SB on this one. The only thing I would suggest is to make sure all joints are tight because if there is a leak in the suction line then the pump will not draw properly. But again, what was the original problem that called for replacing pipes?
